“The Library of Congress celebrates its 214th birthday today. Founded on April 24, 1800, thanks to an appropriation approved by Pres. John Adams of $5,000 for the purchase of “such books as may be necessary for the use of Congress.” What started with a whopping 740 books and three maps has evolved to more than 158 million items, including more than 36 million books and other print materials, 5.5 million maps, 69 million manuscripts, 13.7 million photographs, 6.7 million pieces of sheet music and 3.5 million recordings.” (via Library of Congress Blog)
